Program/Erase Resume
RESUME Operation
To resume a suspended ERASE or PROGRAM operation, issue the RESUME command
to any device address. The ERASE or PROGRAM operation continues where it left off,
and the respective status register suspend bit is cleared. Issuing the RESUME command
does not change the read mode.
When the RESUME command is issued during a simultaneous erase suspend or pro-
gram suspend condition, the PROGRAM operation is resumed first. Upon completion of
the PROGRAM operation, the status register should be checked for any errors, and
cleared if needed. The RESUME command must be issued again to complete the ERASE
operation. Upon completion of the ERASE operation, the status register should be
checked for any errors, and cleared if needed.
